What is Google Voice?

Users can set up a new phone number or use an existing phone number to set up a voicemail box through Google. Users can view voicemails as text messages, text online or listen to them from their phones. Users can set up one number to ring on multiple phone lines. They can also set up a â€œDo not disturbâ€ rule, which sends calls directly to voicemail. Users can also send/receive text messages.

Why is this useful?

Users are able to collaborate with group members or contact other users for homework help without having to give out their own phone numbers. They could also set up their Google Voice phone number to ring on multiple phones, insuring that they are able to receive important calls.
